Help Identifying algae

[hoskyfull]

Hola,


I recently got new live rock and this algae started growing. I just want to know if it’s OK or if it’s a bad one that I should get rid of. Thank you!

it looks like ulva / sea lettuce. Herbivore fish love it, but it will grow out of control if you let it. I'd remove manually and add an herbivore that will eat it if your tank has room.

Hermit crabs will eat it, as will herbivorous snails and urchins. My yellow tang mows it down, but that is not an option in a tank your size.

I bet a lawn mower blenny would love that stuff.
